In every Indian soap, there are villians and most of them are women shown to be bitching around. There would be a lot of difficulties to try to move a story forward without something at least a little bad creating some conflict.
Razia is doing this for some ulterior motive and if she's ready to go to this extent, it must be pretty big. But agreed that she's borderline evil, if not evil right now. But then again, desperate times calls for desperate measures.
Haseena is pure evil.
Shireen isn't evil at all. She's just plain dumb most of the time.
Rashid isn't evil either. He's something worse – he's a spineless man that cannot stand up for something he loves. But still not evil.
For all the girls in the family, you have to understand that this is a very conservative Muslim family. And if your own father is practically in debt to a man who's house you've been living inside for all your life, you can't really go against that person without some hard core proof to prove your point. And that's why Nikhat isn't speaking up.
What Humaira did today was too extreme for me. But again, if you've grown up you're whole life being so sheltered and only loved one person your whole life. For that girl to lose her childhood love and drop so low in the eyes of all her family, that's like stealing everything she's ever owned. It was a big step. But I believe she will be able to stop the engagement with Ayaan and she will stand up.
I think showing realities of a village is not really that bad. It does happen and it can happen, so why not show it? Just look at the infamous Delhi rape case. It's utterly disgusting but it's reality and if they want to show this side of an Indian culture, it doesn't mean they're showing them in negative light. While one girl was shown to be weak and committing suicide, Zoya was also another Muslim girl who was shown to help her and not care for her own life.
I think given time, the show will slowly change and the women who seem feeble right now will become stronger and develop a voice of their own. Just because a few characters are evil doesn't mean things can't change!
